Answer:
V = 21145.01 mm³
Step-by-step explanation:
Given that:
The radius of the gumball = 30 mm
The radius of the spherical hollow-core = 28 mm
Consider the radius of the gumball to be
and the radius of the spherical hollow-core to be
. Then;
The volume of the gumball can be determined by using the formula of a sphere.


V = 21145.01 mm³
